GS1247 VPA 139 Lango Safe Water Project

Audit Analysis

The Lango Safe Water Project (VPA 139 under PoA GS1247) has verified additionality and no reversal events, but is undermined by an unjustified 0% leakage deduction, declining operationality (72%), recurring water quality failures, and numerous unresolved data-quality issues across monitoring reports. The project delivers safe water as an avoidance-type credit, which limits permanence risk, but the breadth of corrective actions and contradictions between documents raises meaningful concerns about the robustness of the underlying MRV data.

Project Description

Red Flags

• ⚠Leakage deduction reduced from 5% (PDD, 2023) to 0% (verification report, 2024) with no documented justification; the most recent verification report (2025) states leakage is 'not addressed'
• ⚠Operationality dropped to 72% (16,883 breakdown days) with 5 boreholes inactive and 6 failing water quality tests (coliform traces) in the latest monitoring period
• ⚠Usage rate declined from 99.5% (2025-02 monitoring report) to 87.5% (2025-12 monitoring report), suggesting deteriorating performance
• ⚠12 contradictions identified across documents, including conflicting ER figures (6,104 vs 51,658 tCO2e), leakage treatment, fNRB method, and crediting period start dates
• ⚠Multiple open Forward Action Requests (FAR 01–05) remain unresolved, including VPA-level SDG indicator evaluation and fNRB recalculation
